Description

Technical Field

[0001] This utility model belongs to the field of charging protection technology, specifically a charging protection device for an inspection robot. Background Technology

[0002] With the continuous improvement of industrial automation, inspection robots are being used more and more widely in the industrial field. To ensure uninterrupted operation, a reliable charging system is crucial. Complex industrial environments contain large amounts of dust, oil, metal shavings, and other contaminants, and may also be accompanied by adverse factors such as high temperature, high humidity, and electromagnetic interference. Traditional charging methods lack effective protection, easily leading to contamination or damage to the charging interface and internal circuitry, thus affecting the robot's normal charging and operational performance. Therefore, there is an urgent need in the market for a charging protection device for inspection robots.

[0003] Meanwhile, the patent specification with application number CN220774822U discloses a charging protection device for an inspection robot, "including a socket with an eccentrically arranged interface and a cover that can be opened and closed covering the interface end of the socket; a protective cavity is formed inside the cover that can rotate circumferentially with the interface end of the socket, and a notch is arranged on the protective cavity, which can be aligned with the interface for plug insertion; the cover and the socket are also provided with elastic braking elements that can restrict each other's circumferential rotation and opening and closing, and the operator operates the cover and the socket to rotate relative to each other, so that the interface and the notch can be in two states: misaligned and aligned. When in the aligned state, the plug is inserted into the interface through the aligned part for charging. When in the misaligned state, the interface end of the socket and the cover enclose a sealed protective cavity that can protect the interface of the socket."

[0004] In the current inspection robot charging device, the charging interface is usually directly exposed during use, lacking an effective protective structure. This can easily lead to personnel accidentally touching the socket, posing a risk of electric shock. Secondly, the exposed charging interface is susceptible to the intrusion of external dust, moisture and other impurities, which not only affects charging efficiency, but may also cause short circuits and other malfunctions in the charging interface in the long run.

[0005] Therefore, a charging protection device for inspection robots is proposed to address the above problems. Utility Model Content

[0006] To address the problems mentioned in the background art, this utility model provides a charging protection device for inspection robots, which can create a safe and stable operating environment for plugs and sockets, effectively resist damage that may be caused by external factors, improve the stability and safety of charging, and reduce short circuits and other faults caused by long-term exposure of the charging interface.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a charging protection device for an inspection robot, comprising a wall, an insert plate body installed at one end of the wall, a rectangular groove on one side of the insert plate body, a protective shell on the inner surface of the rectangular groove, two snap-fit ​​mechanisms at the end of the protective shell corresponding to the rectangular groove, the snap-fit ​​mechanism comprising a first vertical plate, the first vertical plate being fitted into one end of the protective shell, an installation groove at one end of the rectangular groove, a second vertical plate fixedly connected to the inner surface of the installation groove, two pressure springs fixedly connected to one end of the second vertical plate, two clamping plates rotatably connected to one end of the second vertical plate, both clamping plates being semi-circular, a horizontal plate fixedly connected to the opposite ends of the two clamping plates, one end of the two horizontal plates being fixedly connected to the two pressure springs respectively, and a clamping block fixedly connected to one end of the first vertical plate for use with the two clamping plates, the clamping block having a circular cross-section, and both clamping plates having a transition arc facing the clamping block.

[0008] Preferably, one end of the protective shell is fixedly connected to a pull rod, the inner surface of the insert plate body is fitted with a groove for the pull rod, one end of the pull rod that passes through the groove is fixedly connected to a limiting plate, the limiting plate restricts the pull rod from being fully pulled out of the groove, and the pull rod and the groove are in a sliding fit.

[0009] Preferably, there are two pull rods and two rod slots, and the cross-sections of the pull rods and the rod slots are both rectangular.

[0010] Preferably, the protective shell has grooves at both ends, and the two grooves are mirror-distributed.

[0011] Preferably, one end of the protective shell is provided with a plug receiving groove, the outer surface of the protective shell is provided with a wire groove, the inner surface of the wire groove is provided with two elastic sealing strips, and the lower inner wall of the rectangular groove is fixedly connected with a sealing block that matches the wire groove.

[0012] Preferably, one end of the two elastic sealing strips is fixedly connected to the inner surface of the groove, and the two elastic sealing strips are mirror-distributed, and both elastic sealing strips are wool strip type sealing strips.

[0015] Preferably, both clamping plates are semi-circular with a diameter equal to the cross-sectional diameter of the clamping block.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. By setting up a snap-fit ​​mechanism, this utility model can provide good protection for the charging interface on the plug body under the synergistic action of components such as pressure spring and clamp. When the protective shell is closed, the clamp and clamp work together to create a safe and stable operating environment for the plug and socket, effectively resisting damage that may be caused by external factors, and improving the stability and safety of charging.

[0018] 2. This utility model, by setting a plug receiving groove, a wire groove, and an elastic sealing strip on the protective shell, can effectively prevent dust, moisture, and other impurities from entering the socket area under the action of the elastic sealing strip in the wire groove, protect the socket from the influence of the external environment, enhance the sealing effect of the device, and reduce short circuit and other fault problems caused by the charging interface being exposed to the outside for a long time.

[0019] It is particularly important to emphasize the smooth and stable engagement of the locking mechanism. After engagement, the spring only requires a small force to lock in its original position, avoiding prolonged high compression of the spring and extending the service life of the locking mechanism. At the same time, the locking mechanism uses a clamping structure to engage, providing a tension force on the protective shell, resulting in a better sealing effect of the sealing layer on the outer edge of the protective shell. It can accurately apply appropriate pressure to the sealing layer, preventing damage or gaps caused by excessive or insufficient pressure. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figures 1 to 5 As shown, this utility model provides a charging protection device for an inspection robot, including a wall 1, a plug plate body 2 installed at one end of the wall 1, a rectangular groove 9 opened on one side of the plug plate body 2, a protective shell 3 provided on the inner surface of the rectangular groove 9, and two snap-fit ​​mechanisms 5 provided at one end of the protective shell 3 corresponding to the rectangular groove 9.

[0028] The snap-fit ​​mechanism 5 includes a first vertical plate 52, which is engaged with one end of the protective shell 3. A mounting groove 10 is formed at one end of the rectangular groove 9. A second vertical plate 56 is fixedly connected to the inner surface of the mounting groove 10. Two pressure springs 55 are fixedly connected to one end of the second vertical plate 56, and two clamping plates 51 are rotatably connected to one end of the second vertical plate 56. Both clamping plates 51 are semi-circular, and their diameters are equal to the cross-sectional diameter of the clamping block 53. This ensures a precise snap-fit ​​when the clamping block 53 is inserted between the two semi-circular clamping plates 51 due to their equal diameters. It should be noted that "equal diameters" refers to the inner diameter of the two semi-circular clamping plates 51 being equal to the outer diameter of the cross-section of the clamping block 53. This precision ensures that the protective shell 3 is accurately positioned after being installed on the rectangular slot 9, preventing any shaking or displacement due to size mismatch. A horizontal plate 54 is fixedly connected to one end of each of the two clamping plates 51 facing away from each other. One end of each horizontal plate 54 is fixedly connected to two pressure springs 55. A clamping block 53, used in conjunction with the two clamping plates 51, is fixedly connected to one end of the vertical plate 52. The clamping block 53 has a circular cross-section, and the ends of both clamping plates 51 facing the clamping block 53 are rounded. This device facilitates the installation and removal of the protective shell 3 and ensures that the protective shell 3 is stably fixed on the rectangular slot 9 during normal use, preventing accidental opening and protecting the insert plate from external factors such as dust and moisture. It also prevents personnel from accidentally touching the insert plate and causing danger.

[0029] Specifically, one end of the protective shell 3 is fixedly connected to the pull rod 7, and the inner surface of the insert plate body 2 is fitted with the rod groove 15 for the pull rod 7. The end of the pull rod 7 that passes through the rod groove 15 is fixedly connected to the limiting plate 8. The limiting plate 8 restricts the pull rod 7 from being completely pulled out of the rod groove 15. The pull rod 7 and the rod groove 15 are in sliding fit. There are two pull rods and two rod grooves. The cross-sections of the pull rod 7 and the rod groove 15 are both rectangular, which makes it convenient for users to open the protective shell 3. The design of the limiting plate 8 at one end of the pull rod 7 restricts the range of motion of the pull rod 7 and ensures that it will not fall off the insert plate.

[0030] like Figures 1 to 5 As shown, both ends of the protective shell 3 are provided with grooves 4, and the two grooves 4 are distributed in a mirror image. The protective shell 3 can be opened through the grooves 4.

[0031] Furthermore, one end of the protective shell 3 is provided with a plug receiving groove 11, and the outer surface of the protective shell 3 is provided with a wire groove 12. The inner surface of the wire groove 12 is provided with two elastic sealing strips 13. The lower inner wall of the rectangular groove 9 is fixedly connected with a sealing block 14 that is compatible with the wire groove 12. The sealing block 14 can be inserted into the wire groove 12 to increase the sealing performance of the protective shell 3. One end of the two elastic sealing strips 13 is fixedly connected to the inner surface of the wire groove 12, and the two elastic sealing strips 13 are mirror-distributed. Both elastic sealing strips 13 are wool strips. The wool strips can improve the sealing performance of the wire groove 12 and better protect the inside of the wire groove 12 from the influence of the external environment.

[0032] It is worth noting that the outer edge of the protective shell 3 is provided with a sealing layer 6. The sealing layer 6 is made of waterproof, moisture-proof and insulating silicone material. Its thickness is evenly distributed at the joint between the protective shell 3 and the rectangular groove 9. It can protect the plug from water and moisture corrosion and extend the service life of the plug. When the protective shell 3 is installed in place, the various parts in the snap-fit ​​mechanism 5 fit together tightly, so that the connection between the protective shell 3 and the rectangular groove 9 is tight and seamless. This tight connection provides a solid foundation for the sealing layer 6 to play its role, so that the sealing layer 6 can fit better at the joint between the protective shell 3 and the rectangular groove 9, and avoid the sealing gap caused by the loosening of the protective shell 3.

[0033] Working principle and process: First, the protective shell 3 is pulled out through the groove 4. The protective shell 3 drives the pull rod 7 and the limiting block to slide inside the wall 1. As the protective shell 3 moves, it will cause the clamping block 53 to separate to both sides. As the clamping block 53 separates, it will gradually squeeze the clamping plate 51, so that the pressure plate overcomes the elastic force of the pressure spring 55 and separates, thereby releasing the locking between the protective shell 3 and the plug body 2. After opening the protective shell 3, the socket in the rectangular groove 9 on one side of the plug body 2 is exposed. The charging plug of the inspection robot can be inserted into the plug body 2 to start charging. Then, the charging cable is placed in the cable groove 12. The two elastic sealing strips 13 on the inner surface of the cable groove 12, because they are mirror-distributed and are wool strip sealing strips, can tightly fit the charging cable and effectively prevent dust, moisture and other substances from entering the plug receiving groove 11. After charging starts, press the protective shell 3. When the protective shell 3 closes, the clamping block 53 at one end of the vertical plate 52 will squeeze the two clamping plates 51, so that the clamping plates 51 overcome the elastic force of the pressure spring 55. The spring 55 rotates and separates due to the elastic force of the clamping block 53. After the clamping block 53 passes through the clamping plate 51, the pressure spring 55 resets and pushes the clamping plate 51 back to its original position. The clamping plate 51 then locks the clamping block 53, thereby securing the protective shell 3 onto the rectangular groove 9. During this process, the pressure spring 55 is only significantly affected by the elastic force change during the movement of the clamping plate 51, i.e., during the opening and closing operation of the protective shell 3. When the protective shell 3 is closed or fully open, the pressure spring 55 is in a relatively stable stress state and will not experience excessive fatigue wear due to continuous dynamic changes, thus effectively extending the life of the pressure spring 55. Throughout the process, the sealing layer 6 on the outer surface of the protective shell 3 is made of waterproof, moisture-proof, and has good insulation properties. It is evenly distributed at the contact point between the protective shell 3 and the rectangular groove 9, effectively preventing external moisture, dust, etc. from entering the rectangular groove 9 and affecting the normal use of the plug body 2. At the same time, its good insulation properties also ensure the safety of the charging process.
